2017 Astronomical Events Check out our calendar of some of astronomical events for sky watchers. Most of these natural occurrences can be observed with the naked eye but use a pair of binoculars or a telescope for best viewing.
This color image of Io, acquired by the Galileo spacecraft in shows volcanic plumes on the bright edge of the moon, erupting over a volcanic depression named Pillan Patera. The plume rises some 86 miles high into space. Photo by NASA/JPL/Univ/Arizona
ABOUT THIS IMAGE: An image of Jupiter in visible-light from NASA's Hubble Space Telescope (HST) on May 2007 showing the turbulent pattern generated by the two plumes at the upper left part of Jupiter. Object Name: Jupiter
Astronomers using the NASA/ESA Hubble Space Telescope have, for the first time, determined the true color of a planet orbiting another star. If seen up close this planet, known as HD would be a deep azure blue, reminiscent of Earth’s color.
Astronomers have detected the smallest alien planet yet to be directly photographed by a telescope on Earth, a methane-shrouded gas giant much like a young Jupiter. The planet 51 Eridani b orbits a star 96 light-years from Earth and resembles a young Jupi
This is an artist's interpretation of the brown dwarf Gl 229B. It has a dull red color that the eye can see with the luminosity coming out of the infrared. There are some magnetic spots seen on this image as it is thought that younger brown dwarfs posses magnetic fields. This dwarf is to be said 40 AU away. Image by Pat Rawllings
As the New Horizons spacecraft approached Jupiter en route to Pluto in February Chandra took exposures of the gas giant. The purpose of the Chandra observations is to study the powerful X-ray auroras observed near the poles of Jupiter.
